citizen of the 1 United States, 1 resident .ofthe'borough of Manhattan, 'c tyf county,

5 and State of-New Y ork,have inve'nte'd certain; new'and useful In'i rovenients in Motor Suspension T j --lThis invention relates to improvements 1n motor suspension and itsprinci-pal object isito providela means whereby*the=weight of the motor is utilized to maintain the driving belt in tension thereby eliminating the necessity of providing separate tension dewees. :7

Another object of the invent-ion is to provide a device which may be hung from a suitable support or may be reduced to stand upon a support without in any way impairin its operation.

%till another object of the invention is to provide a novel means for swingably securing the motor supporting frame in such a manner as to prevent it from becoming disengaged from the support.

A. further and more specific object of the invention resides in theprovision of an adjustable supporting means for the motor su porting frame.

ith these and other objects in view the invention consists in the novel construction, combination and arrangement of parts which will be fully set forth in the following specification, claimed and illustrated in the accompanying drawings in which Fig. 1 is a perspective view of this improved motor suspension.

Fig. 2, is a. side. view of a portion thereof showing the device supported from below.

Fig. 3, is a side view of the modified form of motor suspension and Fi 4, is a perspective view of an adjustalile supporting element used in conjunction with the device.

Referring to the drawings in detail the numeral 5 designates the hanger or supporting element constituting a substantially inverted U-shaped member 6 having extending horizontally between its arms a bar 7 which constitutes the hanger bar upon which the device is swingably supported. A spacer 8 is adapted to fit around the bar 7 at a point intermediate its ends and secured to said s acer is a plate 9, the opposite extreme end s 10 of which project beyond the I Y I ("if-the spaceris forg a purpose to'-'bemore Be it-known thatI, VIoroa-GFELiLis, a

fully hereinafter described. A set'lscrew9 passed through. the .plate .9 and spacer 10 and engages the; bar 7 to prevent? sidewise ji movement of the spacer and the hooks.

"J The motor 11' is. supportediina substantially rectangularframe .12 having secured to 'its" rear ;Sld6 standards 13,- the extreme ends of whlch are bent asat-14 to'provide hooks for 1 engagement over-the hanger bar It will be understood that the extreme inneredgesjof the hooks 11 engage; the ends jofithespacerfl and when in thisposition *itiwillfbe obvious that theendsilO of -the p'lat9 will partially overlie and prevent. saidhooks from of engagement with the bar 7.

Formed on the standards 13 in spaced relation to the hooks 14 are oppositely turned hooks 15 which are adapted to engage the hanger bar 7 when the device is used as illustrated in Fig. 2.

In order to limit the swinging movement the hooks 14 jumping out of the device, a bar 16 is adjustably secured in straps 17 to the front of the frame 12 and its upper end is provided with a hook 18 which is adapted to be received in a yoke 19, which may be attached in any suitable manner to a stationary support. It will thus be obvious that should the belt 20 break or slip off of its pulley, the motor will tend to swing downwardly around the bar 7 and the length of movement will be limited by the engagement of the hook 18 with the yoke 19.

In the modified form of the device illus trated in Fig. 3, the motor 21 has secured to its base plate suitable standards 22 which are provided with yokes 23 and 24: corresponding respectively with the yokes 14 and 15 of the standards 13. These yokes are adapted to engage the hanger bar 7 mounted in the hanger 5, and the same means as previously described is used for securing the hooks against accidental displacement. In this type of device it will be seen that should the belt 25 break, the motor will be free to swing and no limiting device is used.

In the modified form of hanger illustrated in Fig. 1, a suitable U-shaped stationarjy.

ber 27 and it will be obvious that by adjusting the tension of the bolts 28 the device may be held in various adjusted positions.

In use the device is supported in the manner shown and it will be obvious that when a load is placed on the belt 20, the belt will be held under tension by the weight of the 'motor thereby avoiding the necessity of providing separate tension devices and since the load ordinarily varies according to the number of machines in operation it will be seen that the motor will be free to swing back and forth and yet at all times will maintain sutficient tension on the belt to drive the mechanism.

While in the foregoing there has been shown and described a preferred embodiment of this invention it is to be understood that certain minor changes in the details of construction, combination and arrangement of parts may be resorted to.

What is claimed is 1. Means for supporting'a belt operating member comprising a supporting bar, hooks suspended from said bar, a housing for said belt operating member supported by said hooks, and a yoke and a hooked bar for limiting the movement of straps upon said housing, is adjustably secured.

2. A mounting for a belt operating motor which comprises a housing for said motor, a support for said housing comprising a bracket, a rod in said bracket, hook members connecting said rod and said housing, said hook members being suspended from and adapted to have movement around said rod, and a plate associated with said rod for preventing the accidental disengagement of said hook members and means for limiting the swinging movement of said housing.

3. A mounting for a belt operating element which comprises a housing therefor, a supporting rod, .hook members suspended from said rod and connecting said housing and said rod, said housing being adapted to swing about said rod, means for limiting said swinging movement, a spacer for preventing movement of said housing longitudinally of said rod, and a plate for retaining said hook upon said rod.

Signed in the city, county'and State of said housing and in which said bar New York, this 22d day of December, 1920.
